What does “Equipotential surfaces” actually mean in Electrostatic Potential & Capacitance, and why does it matter for NEET?
Moving a charge along an equipotential surface requires no work by or against the electrostatic field. Electric-field lines cross equipotentials at right angles.
In simple words: Moving a charge along an equipotential surface requires no work by or against the electrostatic field. Electric-field lines cross equipotentials at right angles. Getting Equipotential surfaces clear matters because NEET questions on Electrostatic Potential & Capacitance usually test this idea directly, not just a formula you memorised.
Key point
Equipotential surfaces
Common mistake
thinking zero work along the surface means the electric field is zero there.
Memory tip
the field may be strong, but it has no component along an equipotential.
